Understanding Time Tables Counting On

Hello, Year 4! Today, we’re going to learn about something really important in maths called “time tables counting on.” This means we will learn how to use our times tables to add numbers quickly by counting on. Let’s break it down step by step!

What Are Times Tables?

First, let’s remember what times tables are. Times tables show us how many groups of a number we have. For example, if we look at the 2 times table:

  • 2 × 1 = 2
  • 2 × 2 = 4
  • 2 × 3 = 6
  • 2 × 4 = 8
  • 2 × 5 = 10

When we say “2 times 3,” we mean 2 groups of 3, which gives us 6!

Counting On with Times Tables

Now, let’s see how we can use times tables to count on. Instead of adding numbers one by one, we can jump ahead using our times tables.

Example 1:

Let’s say you have 6 and you want to add 4 more. Instead of counting 6, 7, 8, 9, 10, you can think about the 2 times table:

  • 2 x 1 = 2
  • 2 x 2 = 4
  • 2 x 3 = 6
  • 2 x 4 = 8 (this is 6 + 2)
  • 2 x 5 = 10 (this is 6 + 4)

So, 6 + 4 = 10!

Key Rules

  1. Know Your Times Tables: The better you know your times tables, the easier it will be to count on.
  2. Use Jumps: Instead of adding each number, think about how many groups you can make with your times tables.
  3. Practice, Practice, Practice: The more you practice, the better you will get!

Tips and Tricks

  • Visual Aids: Use number lines or counters to help you see the jumps.
  • Grouping: If you are adding 3 + 3 + 3, you can think of it as 3 times 3 instead!
  • Games: Play games that involve counting on and using times tables to make it fun!
